Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 4, an automatic opening and closing device for a thermal insulation cover of a feeding port at the top of a thermal insulation furnace comprises an electric hoist 3, a guide frame 1 and a slide bar 2, wherein the guide frame 1 is arranged on one side of the furnace body 100, which is far away from the hinged side of a furnace cover 200, the slide bar 2 is fixed at the upper end of the furnace cover and extends to one side of the guide frame 1, the electric hoist 3 is arranged above the guide frame 1, the traction end of the feeding device is fixed with a feeding device 4 through a chain sling 31, the upper part and the lower part of the feeding device 4 are respectively provided with an upper roller 51 and a lower roller 52, the feeding device 4 is arranged on the guide frame 1 in a sliding manner through an upper roller 51 and a lower roller 52, the upper part and the top end of the guide frame 1 are respectively provided with a notch 11 for separating the lower roller 52 and a top plate 6 capable of being abutted against the upper roller 51, the feeding device 4 is driven by the electric hoist 3 to move upwards to enable the upper roller 51 to be abutted against the top plate 6 and rotate and incline around the top plate 6, and the upper end of the feeding device is abutted against the slide rod 2 to jack up the furnace cover.
The ascending and descending of the feeding device are controlled by an electric hoist, the motion trail of the feeding device is controlled by a guide frame, when the feeding device contacts a slide bar in the ascending process, the slide bar is lifted upwards, the furnace cover turns into the turning motion by taking a hinge as a rotating shaft, and the cover opening is finished; when an upper roller of the feeding device rises to the top plate, the sling chain is continuously tightened, the lower roller is separated from the guide frame through the gap, and at the moment, the ascending linear motion of the feeding device is changed into the overturning motion with the upper roller as a rotating shaft, so that the feeding is completed; the lifting chain automatically stops when rising to a positioning point (a limit switch), and at the moment, the furnace cover is also opened to the maximum; after the feeding is finished and the sling chain descends, the feeding device can generate a turning force to turn the feeding device to a vertical state, the lower roller automatically enters the guide frame from the notch, and the feeding device is converted into descending linear motion; and (4) along with the descending, the furnace cover losing the jacking force also automatically descends until the furnace cover is completely closed, and the feeding action is finished.
The feeding device 4 comprises a feeding basket 42 and a hanging bracket 41, the feeding basket 42 is arranged on the guide frame 1 in a sliding manner through an upper roller 51 and a lower roller 52 arranged on the feeding basket, the hanging bracket 41 is hinged on the feeding basket 42 and connected with the hanging chain 31, and the rotary feeding action of the feeding basket can be completed through the hanging bracket hinged on the feeding basket.
